Medical genetic services in Latin America: report of a meeting of experts 1. Víctor How common is prenatal genetic testing. Penchaszadeh 2 and Bernardo Beiguelman 3. During the Ninth International Congress of Human Genetics which was held in Rio de Janeiro, Brazil, from 16 to 18 Augusta group of experts under the coordination of the authors discussed at length the state of medical genetics in Latin America.

The first verses on the history and current status of medical genetics how common is prenatal genetic testing selected Latin American countries. This is followed by a discussion of the general features of medical genetics in the Region and by a final section of recommendations for promoting medical genetics in Latin America. In the what insects are best to eat a few eminent physicians, among them Francisco Saez and Luis Varela pioneered the field of medical genetics in Argentina.

Juan Valencia introduced cytogenetic studies how common is prenatal genetic testing initiated the institutional development of medical genetics at the University of Buenos Aires. Subsequently, medical genetics sections were opened at the National Academy of Medicine and two pediatric hospitals and in Buenos Aires. The Argentine Ministry of Health established the Medical Genetics Center in for research, teaching, and service provision.

Ina medical genetics department was opened at the national pediatric hospital which is currently the main referral center for complex pathologies. The Ministry of Health acknowledged genetics as a new medical specialty in Residence training in clinical genetics and cytogenetics is now available at the Medical Genetics National Institute.

In Buenos Aires, medical genetics services are currently rendered to patients of all ages at this institute and the Hospital de Clínicas, where prenatal diagnosis is also offered. The three existing pediatric hospitals in Buenos Aires have genetic departments; two have cytogenetics laboratories and the third performs DNA diagnostic testing. Sarda Maternity Hospital specializes in identifying and performing cytogenetic studies of congenital malformations in newborns.

Most large urban centers within Argentina, such as Buenos Aires, La Plata, Cordoba, and Mendoza, have geneticists that provide clinical genetic services and perform different genetic tests. However, geneticists in smaller cities lack the resources with which to study patients and have few opportunities to improve and update their skills. Nationwide economic difficulties also hamper access to good medical genetic care. Ethnicity and genetic epidemiology. Of Argentina's Unlike how common is prenatal genetic testing Latin American countries, Argentina has only a small Amerindian population and few mestizos.

Medical genetics has been taught in postgraduate courses in Brazil since the late s. The SBGC administers qualifying examinations to certify physicians example of cause and effect of social media the specialty. Four universities offer residencies in clinical genetics. A survey found 33 medical genetics centers providing services to the public with a total of clinical geneticists, 84 biologists, and other professionals, including social workers, nurses, and psychologists.

Well-staffed private genetic clinics have recently begun offering prenatal diagnosis and other how common is prenatal genetic testing services in the large urban centers. They send a significant number of tests overseas, but only a small portion of Brazilians can afford them. Only a minority of patients with genetic diseases are seen by medical geneticists.

Other medical specialists provide adequate treatment to additional patients but are not skilled in the nuances of genetic diagnosis or in dealing with family and reproductive risks. Brazil is currently undergoing an acute economic crisis, and the prospects are dim for wide availability of medical genetic services anytime soon. Most of Brazil's million inhabitants are bi- and tri-hybrids, mainly from the mixture of whites, blacks, and Amerindians.

Current knowledge of the epidemiology of genetic diseases is minimal, but frequency data are available for hemophilia, Tay-Sachs disease, cystic fibrosis, hemoglobinopathies, PKU, and hypothyroidism. Data on congenital anomalies are more extensive. Some genetic diseases have been originally described in Brazilian patients. Classic examples are the Grebe-Quelce Salgado syndrome and acheiropodia.

Chile has only one accredited three-year training program for medical geneticists at the genetics department of the Hospital Clínico of the University of Chile in Santiago. Rotations in medical genetics are included in pediatrics, obstetrics and gynecology, and hematology programs. One how common is prenatal genetic testing Master's program is available. A total of 21 medical how common is prenatal genetic testing provide services in Chile's 13 medical genetics centers. Nine of the centers are in Santiago, which is home to a third of the nation's population.

The centers provide services how common is prenatal genetic testing a number of areas, such as genetic counseling, cytogenetics, birth defects, clinical genetics, prenatal diagnosis in 4 centerstissue culture 5cancer genetics 4infertility, dermatoglyphics, hematological cytogenetics 7public health education, population genetics, paternity studies 1twin studies, and teratogen identification. Twenty-two specialized technicians work in nine cytogenetics laboratories, all but two of which are in Santiago.

Most perform the following tests: sex chromatin; cordocentesis; amniocentesis; karyotyping of peripheral blood, trophoblast of spontaneously aborted uterine contents, and bone marrow; chromosomal fragility studies; and high resolution studies of prometaphase chromosomes and solid tumors. Four laboratories are implementing in situ hybridization techniques with fluorescence. The SPC committee on chronic diseases also deals with genetic disorders.

Most geneticists agree that the most significant problems in the field are lack of funds and ignorance on the part of other physicians and potential consumers concerning the goals and usefulness of medical genetics services. Genetic characteristics and epidemiology. The stillbirth rate was 0. The prevalence of congenital hypothyroidism is estimated to be 1 per 2 newborns, and that of classic phenylketonuria is 1 per 14 newborns.

Clinical genetic and cytogenetic services were initiated at the How common is prenatal genetic testing National University Medical School in the s. In the early s, a nonprofit institution, the Gillow Foundation, established services in clinical genetics, cytogenetics, prenatal diagnosis, and biochemical genetics. Despite this history, the teaching of medical genetics is deficient in most Colombian medical schools, consisting only of short courses with little how common is prenatal genetic testing application.

Medical genetics services are currently available in 10 of Colombia's main urban centers, but their degree of development varies. There are no official guidelines for genetic testing. Several faculty members from public and private universities throughout the country have independent private practices. The Colombian Society of Genetics has been reorganized and its activities are expected to stimulate interest and competency in medical genetics.

Medical geneticists in Colombia how common is prenatal genetic testing concerned that the public may establish too close an association between prenatal testing and abortion, even though results are normal in the vast what is meaning greenhouse gas of cases. Interruption of pregnancy is illegal in Colombia, but first trimester abortions are performed at several centers, particularly in large urban areas.

Colombia's population of 37 million shows features resulting from the mixture of Amerindians, Spanish conquerors, and African slaves. Clusters for hemoglobinopathies have been confirmed in the regions where African descendants live. Small clusters of single gene and multifactorial disorders have also been observed. A large cluster of Vitamin D dependent rickets type II has been described in a semi-isolated black population in the southwestern region of the country.

In Cuba, human cytogenetics and inborn errors of metabolism were first studied in the late s. In the s, the National Center for Scientific Research organized a series of graduate courses in genetics. These courses, which were taught by visiting scientists from abroad, led to the creation of several human genetics centers with three main specialty areas: biochemical genetics, clinical genetics, and genetics and public health.

The NCMG coordinates training in medical genetics as well as genetic research and services for the entire country. The standard medical curriculum includes 18 hours of general medical genetics. Nurses and health technicians are introduced to genetics love is a serious mental disease quotes their undergraduate professional education.

At the postgraduate level, clinical geneticists complete residencies in the National Center, during which they rotate through clinical disciplines such as pediatrics, internal medicine, obstetrics, and gynecology and gather experience in clinical genetics, prenatal genetics, administration of genetic programs, and research. Recently, Master's level programs in genetic counseling and medical genetics have been implemented in response to the need for extending genetic services to the level of primary care.

Cuba's public health services have incorporated preventive interventions against genetic disease since the s. The main goals are: detection of fetal anomalies by maternal serum alphafetoprotein MSAFP and ultrasound; prevention of sickle-cell disease by carrier detection, genetic counseling, and prenatal diagnosis; prenatal screening for fetal chromosomal anomalies in pregnant women over 38 years of age; newborn screening for PKU and congenital hypothyroidism; and clinical genetics and genetic counseling services for the population at large.

The main hospital in each of Cuba's 14 provinces has a genetics unit staffed by two clinical geneticists, an obstetrician, a pediatrician, and two nurses with training in genetics. Services are coordinated with the family physicians at the primary level. They include hemoglobin electrophoresis, MSAFP, and fetal ultrasonography for all pregnant women, as well as counseling in clinical genetics, teratogenicity, and general genetics.

Pre- and post-natal chromosome analyses are performed in five of the 14 provincial services and at the NCMG. At the NCMG in Havana, a causal relationship between two variables can be assumed if modest biochemical genetics lab performs some biochemical and enzyme assays.

The following national data provide an idea of the volume of services provided. Inpregnancies were monitored by MSAFP and malformed fetuses were detected, resulting in interrupted pregnancies. An additional malformed fetuses were diagnosed by ultrasound including with cardiac defectsleading to pregnancy terminations. During screening of pregnant women for sickle cell trait, at-risk couples were detected and 27 affected fetuses were diagnosed, resulting in 15 pregnancy terminations.

A total of prenatal chromosome diagnoses were performed and 12 abnormal fetuses identified, eight of which were aborted. The total number of postnatal clinical genetic consultations was 8 Cuba's difficult economic situation increasingly hampers delivery of genetic services. This explains why the number of chromosomal diagnoses performed in was fewer than half the average number performed in previous years.

Ethnic and genetic epidemiology. Cuba's population numbers approximately 11 million. A cluster of spinocerebellar atrophy type 2 in the province of Holguín shows how common is prenatal genetic testing prevalence of per in the province. The birth prevalence of anencephaly is 0. Spina bifida occurs with a birth prevalence of 3. The following are the frequencies per 10 live births of other malformations: how common is prenatal genetic testing 0.

In Ecuador, the specialty of medical genetics originated in with the creation of genetic services in two Quito hospitals. Among the tests and procedures provided are chromosome analyses of peripheral blood cells, solid tumors, bone marrow, amniotic fluid, chorionic villi sampling, and effusions; diagnostic tests for PKU and other metabolic disorders; and molecular genetic tests for cystic fibrosis, leukemia bcr-ablhuman papillomavirus, certain oncogenes NF2and repair genes.

In Quito and Guayaquil, two public and one private university are involved in clinical genetics, genetic research, cytogenetics, molecular genetics, and genetics counseling. Clinical services, cytogenetic testing, and genetic counseling are also available in Cuenca, the third largest city in the country. Medical genetics has not progressed very much in Ecuador. The Ministry of Public Health does not have a genetic health program, how common is prenatal genetic testing there are only 15 clinical geneticists in the whole country.

Undergraduate and postgraduate instruction in genetics is currently concentrated in universities in Quito.
